	=== Hardware ===		=== Hardware ===

			* Most robust level of separation.
			* Good option for clients who are large enough to warrant their own server anyway.

	=== Virtualisation ===		=== Virtualisation ===

			* From the operating system point of view, almost the same as hardware (it is sometimes possible to work out that an OS is running on virtualised hardware as opposed to the physical hardware).

	=== Shared hosting ===		=== Shared hosting ===

			* Separate by directories and users.
			* Causes problems if web server does not run as same user as the site owner.
			* Often possible to access other users' data via vulnerabilities, shared directories (e.g. <code>/tmp</code> for sessions).
